Answer:
a. Eric H. Davidson
Explanation:
Eric H. Davidson was a developmental biologist whose work helped to understand gene regulation networks in an evolutionary context, being a pioneer in understanding embryogenesis at the genome level. He especially studied sea urchin development, a model animal for developmental biology and genomics. He focused on the animal's nucleic acid properties through the process of hybridization (which has enabled us to understand molecular interactions during development as a whole system), shedding light on the molecular basis of sea urchin development. Eric H. Davidson also compiled the first list of 'fully sequenced' sea urchin genes, involving especially transcription factors, and their interactions with cis-regulatory sequences.
Answer:
a. Eric H. Davidson
Explanation:
Davidson, a developmental biologist, was a pioneer researcher and theorist of the gene regulatory networks that perform complex biological processes, such as the transformation of a single-celled egg into a complex organism. His work helped to reveal how the DNA sequences inherited in the genome are used to initiate and drive forward the sequence of steps that result in development.
